Such shorthand notations are used for purposes of convenience only and should not be construed to limit the disclosure in any way unless expressly stated to the contrary.

Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

In addition, use of “a” or “an” may be employed to describe elements and components of embodiments disclosed herein. This is done merely for convenience and “a” and “an” are intended to include “one” or “at least one,” and the singular also includes the plural unless it is obvious that it is meant otherwise.

Finally, as used herein any reference to “one embodiment” or “some embodiments” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment disclosed herein. The appearances of the phrase “in some embodiments” in various places in the specification are not necessarily all referring to the same embodiment, and embodiments may include one or more of the features expressly described or inherently present herein, or any combination or sub-combination of two or more such features, along with any other features which may not necessarily be expressly described or inherently present in the instant disclosure.

Referring generally to FIGS. 1 and 2, a mobile self-vending beverage cart 100 is disclosed. The beverage cart 100 may include casters 102, caster lock 104, outlets 106 a-c, latch bars 108, bellow seals 110, handle 112, access hatch 114, raceways 116, and raceway components 118.

In embodiments, the beverage cart 100 may be transportable (e.g., via handle 112) along flat surfaces via casters 102 mounted to its underside; for example, the casters may be locked via caster lock 104 to secure the beverage cart in place. In some embodiments, the casters 102 may be configured for omnidirectional travel. For example, the beverage cart 100 may be proportioned or sized comparably to a galley cart or trolley of standard size, transportable along an aisle within a passenger cabin of an aircraft or other vehicle of sufficient interior size. In some embodiments, the beverage cart 100 may correspond to a standard half-size cart (e.g., FIGS. 1 and 2 then showing an end, rather than a side, of the half-size cart as stowed in a standard size cart bay).

In embodiments, the beverage cart 100 may be configured for the loading and dispensing of canned beverages 120. For example, the interior of the beverage cart 100 may be divided into a group of segmented sections 122 a-c, each segmented section loaded with a particular type (e.g., brand, size) of canned beverage and configured to dispense said beverage via an outlet 106 a-c dedicated to that particular segmented section.

For example, referring in particular to FIG. 2, a quantity of canned beverages 120 (e.g., canned beverage containers, or other like vendable containers having a substantially cylindrical shape) may be loaded into the beverage cart 100 via the access hatch 114. Once loaded into the beverage cart 100, the canned beverages 120 may be capable of gravity-assisted travel along a substantially vertical raceway 116; for example, the raceway may comprise a series of individual interior ramps 118 mounted to interior surfaces of the beverage cart (e.g., one raceway for each segmented section 122 a-c) and extending downward from the access hatch 114 to the outlet 106, where the canned beverages 120 may be individually dispensed from the beverage cart. Each outlet 106 may include a bellow seal 110 enabling the beverage cart 100 to connect, via the outlet, to a freestanding beverage distribution system as described in greater detail below.

In embodiments, each segmented section 122 a-c of the beverage cart 100 may be pre-loaded with a quantity of canned beverages 120. For example, when a canned beverage 120 is dispensed via the outlet 106, the canned beverage 120 a immediately following it may slide into its place, assisted by gravity, until it too is dispensed, the remaining canned beverages following in sequence.

In embodiments, the beverage cart 100 a may be implemented and may function similarly to the beverage cart 100, except that the beverage cart 100 a (or, e.g., one or more segmented sections 122 a-c thereof) may be configured to dispense a canned beverage 124 having a larger diameter 202 than the diameter 204 of the canned beverage 120. For example, the beverage carts 100, 100 a may be configured (via their individual segmented sections 122 a-c) for the dispensing of multiple types, brands, or volumes of alcoholic or nonalcoholic canned beverages 120, 124 having different diameters and/or volumes (e.g., the four can sizes 250 ml/8.45 fl. oz.; 330 ml/11.15 fl. oz; 355 ml/12 fl. oz; and 400 ml/13.5 fl. oz. compatible with the raceways without the need for any additional modification), the interior raceways 116 being sized or dimensioned to fit canned beverages of a given diameter or volume. In some embodiments, the interior raceways 116 may be resized or otherwise modified to accommodate additional types of substantially or partially cylindrical beverage containers (e.g., 125 mL or 175 mL miniature wine bottles; 20 oz soda pop bottles; premixed cocktails and spirits).

In some embodiments, the beverage cart 100 a may include a rear access door 206 (e.g., rear access panel) allowing the loading of a complete segmented section 122 a-c into the beverage cart (e.g., including a raceway 116 loaded with a full complement of canned beverages 120, 124) via the rear access door.

Referring to FIG. 3A, the flap release mechanism 300 is shown. The flap release mechanism 300 may include retaining flap 302, flap retaining catch 304, detached plunger 306, and plunger actuator 308.

In embodiments, the retaining flap 302 may be bottom-hinged (302 a) and spring-loaded to secure the next-to-be-dispensed canned beverage 120 until it is dispensed via the outlet 106. For example, the plunger actuator 308 may be configured for actuation by an appropriately sized spacer mounted on a galley wall (or, e.g., within a beverage dispensing station as described below). Actuation of the plunger actuator 308 may in turn actuate the detached plunger 306 (e.g., detached from the retaining flap 302) into the flap retaining catch 304, driving the retaining flap forward to release the canned beverage 120. The flap release mechanism 300 may enable the use of the rear access door (206, FIG. 2) for loading of a complete, fully loaded segmented section (122 a-c, FIG. 1) into the beverage cart (100/100 a, FIG. 2).

Referring now to FIG. 3B, the flap release mechanism 300 a may be implemented and may function similarly to the flap release mechanism 300 of FIG. 3A, except that the flap release mechanism 300 a may include a mechanically linked retaining catch rod 306 a linked to the retaining flap 302, which drives the retaining flap backwards to release the canned beverage 120.

Referring to FIGS. 4A and 4B, the beverage carts 100 b-c may be implemented and may function similarly to the beverage carts 100, 100 a of FIGS. 1 and 2, except that the beverage carts 100 b-c may be configured for larger groups of outlets 106 and internal raceways (116, FIG. 2) and therefore the dispensing of more types, brands, or sizes of canned beverages (120/124, FIG. 2).

In embodiments, the beverage carts 100 b-c may be respectively sized to accommodate five or six outlets 106 and five or six internal raceways 116. Further, the beverage carts 100 b-c may be configured so that the internal raceways 116 run, and canned beverages 120, 124 are dispensed from the outlets 106, in a transverse direction relative to the handle 112 and the “forward” direction of travel (e.g., perpendicular to the raceways 116 within the beverage cart 100, 100 a shown by FIGS. 1 and 2; “forward” here may refer to the direction in which the beverage carts 100 b-c may most likely be propelled via the handle 112, although the casters 102 may allow for omnidirectional travel). In some embodiments, the beverage carts 100 b-c may include an additional handle 112 a mounted transversely.

In some embodiments, the beverage carts 100 b-c may be configured for stowage within an ARINC standard galley, e.g., provided intermediate retainers are appropriately positioned within the cart bays, allowing the beverage carts 100 b-c to be transported and chilled inflight via the galley refrigeration system.

In embodiments, the latch bars 108 enable the beverage carts 100 b-c (as well as the beverage carts 100, 100 a of FIGS. 1 and 2) to be secured within a dispensing station as described in greater detail below. In some embodiments, the latch bars 108 (or the corresponding latches, as shown below) may require respacing or rail-based mounting to allow for rapid repositioning or installation of the beverage carts 100 b-c within a dispensing station.

Referring to FIGS. 5A and 5B, the beverage carts 100 d-e may be implemented and may function similarly to the beverage carts 100, 100 a of FIGS. 1 and 2, except that the beverage carts 100 d-e may include sliding finger grip catches 502, 502 a-c set into the upper or top surface of the beverage carts, e.g., adjacent to the access door 114.

In embodiments, the sliding finger grip catch 502 may be used to actuate the retaining flaps (302, FIGS. 3A-B), releasing the internal raceways (116, FIG. 2) within the beverage cart 100 d. Similarly, referring in particular to FIG. 5B, the beverage cart 100 e may include three sliding finger grip catches 502 a-c, each finger grip catch configured to actuate a single raceway 116 or segmented section (122 a-c, FIG. 1) of the beverage cart.

Referring to FIG. 6, a beverage dispensing station 600 is shown. The beverage dispensing station 600 may incorporate one or more beverage carts 100 secured therein as well as a counter surface 602, forward wall 604, structural wall 606, cart latch 608, and delivery point shroud 610.

In embodiments, the beverage dispensing station 600 may be embodied in a galley monument or freestanding bar unit permanently or temporarily installed within an aircraft cabin (or within any other like vehicle of sufficient interior size) and capable of accommodating a group of consumers who may select or purchase canned beverages 120 and/or congregate around the beverage dispensing station. For example, the forward wall 604 may include one or more indentations under the counter surface 602 (or may have a generally concave shape) to accommodate seated customers.

In embodiments, one or more beverage carts 100 may be secured to the structural wall 606 underneath the counter surface 602 and connected (at the outlets 106 a-c, FIG. 1) to the beverage dispensing station 600 via the bellow seals 110. For example, the beverage dispensing station 600 may include a rear wall 606 a behind the beverage carts 100, e.g., to conceal the beverage carts from view or define an enclosed compartment within which the beverage carts may be secured. The beverage carts 100 may be secured in place by the cart latches 608 (e.g., engaging with the latch bars 108). In some embodiments the beverage dispensing station 600 may be staffed by an attendant, e.g., stationed behind the rear wall 606 a and controlling the dispensation of canned beverages 120 from the beverage carts 100. Alternatively, customers at the forward end of the beverage dispensing station 600 (e.g., proximate to the forward wall 604) may select a canned beverage 120, which is automatically dispensed from the appropriate beverage cart 100 and delivered to the customer at a delivery point set into the counter surface 602, which delivery point may be partially obscured by the delivery point shroud 610. In some embodiments, the beverage dispensing station 600 may incorporate a card reader (not shown) set into or on the counter surface 602 to allow canned beverages 120 to be charged to customer payment cards, membership cards, or any other like customer card having either a magnetic stripe or integrated circuit (IC) chip readable by the card reader.

Referring now to FIG. 7, the beverage dispensing station 600 a may be implemented and may function similarly to the beverage dispensing station 600 of FIG. 6, except that the beverage dispensing station 600 a may accommodate the beverage carts 100 through a lockable forward wall 604 a.

In embodiments, customers may congregate around the forward wall 604 a and select canned beverages (120. FIG. 6), which are dispensed from the beverage carts 100 and delivered to the customers via delivery points set into the counter surface 602 and partially obscured by delivery point shrouds 610. For example, the beverage dispensing station 600 a may be utilized (e.g., deployed laterally, in line with the aircraft fuselage or vehicle side) to serve standing customers, or in areas where space may be limited (as opposed to the beverage dispensing station 600).

Referring to FIG. 8, the beverage dispensing station 600 is shown.

In embodiments, canned beverages 120 selected by customers may be dispensed from the beverage carts 100 and delivered to the customers via delivery points 802 (e.g., collection points) set into the counter surface 602 of the beverage dispensing station 600. For example, each delivery point 802 may be dedicated to a particular brand or type of canned beverage 120, or dispensable from a particular beverage cart 100. Each delivery point 802 may be partially covered by a delivery point shroud 610; the delivery point shroud may be fashioned of a rigid material and include branded or decorative elements, e.g., bespoke to a particular brand or airline; evocative of a beer pump or soft drink dispenser.

In embodiments, each delivery point shroud 610 may incorporate a downward-hinged panel or flap 804, e.g., to prevent the delivery point 802 from becoming a finger trap risk. For example, the flap 804 may pivot downward to open when a canned beverage 120 is delivered and retract into place (806) once the canned beverage has been retrieved.

Referring to FIGS. 9A and 9B, the selection and delivery mechanisms 900, 900 a are disclosed. The selection and delivery mechanism 900 a of FIG. 9B may be implemented and may function similarly to the selection and delivery mechanism 900 of FIG. 9A, except that the components of the selection and delivery mechanism 900 a may be inverted in configuration.

In embodiments, the beverage dispensing stations 600, 600 a of FIGS. 6 and 7 may incorporate multiple selection and delivery mechanisms 900 therewithin. For example, each selection and delivery mechanism 900 may be dedicated to, and configured to collect (e.g., via a selection device 902) canned beverages 120 dispensed from, a delivery cart (100, FIGS. 6-7) and convey the selected canned beverages (e.g., via a transfer device 904 and can lift device 906) to the delivery point (802, FIG. 8) partially covered by a delivery point shroud 610.

Referring to FIG. 10, the beverage dispensing station 600 a is disclosed.

In embodiments, the selection device 902, transfer device 904, and can lift device 906 of the beverage dispensing station 600 a operate in concert to retrieve canned beverages 120 a-e from the beverage carts 100 and deliver the selected cans to customers at the delivery points 802. For example, the operations of component subsystems of the selection and delivery mechanisms 900, e.g., selection devices 902, transfer devices 904, and can lift devices 906, may be controlled by central control processors housed within the beverage dispensing station 600 a. It should be noted that the can lift device 906 may take many forms and may be configured for the delivery of bottles and other like beverage containers having a substantially or primarily cylindrical shape.

In embodiments, the canned beverage 120 a has been selected by a customer (e.g., attendant, crewmember) and may be transferred via the selection device 902 from the beverage cart 100 f to a shrouded conveyor 1002 a within the transfer device 904. For example, the customer may select the canned beverage 120 a by pressing a selector button 1004 incorporated into the delivery point shroud 610, initiating the dispensing process. Control processors may prevent out-of-sequence operation of the component subsystems and control the delivery of one canned beverage 120 a; within any given set of component subsystems, additional canned beverages may be waiting in the selection device 902 or the transfer device 904 while the can lift device 906 is delivering a canned beverage to the delivery point 802.

In embodiments, the canned beverage 120 b may be transferred (via the conveyor 1002 of the transfer device 904) to the base of the can lift device 906.

In embodiments, the canned beverage 120 c may, at the base of the can lift device 906 c, from a horizontal orientation (e.g., canned beverages 120 a-b) to a vertical orientation compatible with the can lift device 906, e.g., by being upended by a change in angle (1006) at the terminal end of the conveyor 1002 and deposited into a can receiver 1008 at the base of the can lift device 906.

In embodiments, linear actuators 1010 within the can lift device 906 may raise the canned beverage 120 to the delivery point 802. Simultaneously, as the canned beverage 120 d rises toward the delivery point 802, the flap 804 may open to allow the canned beverage access to the delivery point 802 and delivery point shroud 610.

In embodiments, when the canned beverage 120 e arrives at the top of the can lift device 906, the canned beverage may be retrieved from within the delivery point shroud 610 by the selecting consumer, after which the flap 804 may close over the delivery point 802.

Referring to FIG. 11A, the selection device 902 is disclosed.

In embodiments, the selection device 902 may comprise a set of carriers 1102 a-c housed in an outer sleeve 1104, each carrier dedicated to an outlet (106 a-c, FIG. 10) and having an inner sleeve 1106. For example, the selection device 902 may mate with the bellow seals (110, FIG. 1) of the beverage cart 100, providing a transfer port from the outlets 106 a-c of the beverage cart to the conveyor (1002, FIG. 10)) of the transfer device (904, FIG. 10).

Referring also to FIGS. 11B through 11D, within a given carrier 1102 a, the inner sleeve 1106 may rotate (e.g., driven by a stepper motor 1108 and drive sprockets 1108 a). For example, the stepper motors 1108 may be electrically powered and controlled by the control processors of the beverage dispensing station 600, 600 a. The stepper motor drive sprockets 1108 a may project through the carrier 1102 a to a perforated, stamped or molded track in the inner sleeve 1106 to rotate the inner sleeve. The carrier 1102 a may be further insulated via closed cell foam 1110 or any other like sound deadening material, but may include apertures 1112 in both sides.

In embodiments, referring in particular to FIG. 11B, the inner sleeve 1106 may include an aperture 1112 which faces vertically upward to restrain the canned beverages (120 a-e, FIG. 10) within the beverage cart 100.

In embodiments, referring in particular to FIG. 11C, when a canned beverage 120 is selected, the inner sleeve 1106 may be rotated counterclockwise, accepting the canned beverage 120 into the inner sleeve.

In embodiments, referring in particular to FIG. 11D, the inner sleeve 1106 may rotate clockwise (e.g., 190 degrees, or at least 180 degrees from the position shown by FIG. 11C) to transfer the canned beverage 120 to the conveyor 1002 a-e, retaining the subsequent canned beverage (e.g., the next to be dispensed) and presenting a closed face throughout the transfer, from retrieval to dispensing.

Referring to FIGS. 12A through 12C, the transfer device 904 is disclosed.

In embodiments, the conveyor 1002 (e.g., conveyor belt) may be a silicon ribbed conveyor belt driven in a continuous loop by stepper motors 1108, stepper motor drive sprockets 1108 a, and stepper motor drive belt 1108 b. For example, the conveyor 1002 may transfer the canned beverage 120 from the selection device (902, FIG. 11A) toward a can receiver 1008 at the base of the can lift device (906 a-e, FIG. 10). As the canned beverage 120 approaches the can receiver 1008 (e.g., as determined by proximity sensors (not shown)), the angle of the conveyor 1002 may dip sharply downward (1202), transitioning the canned beverage from a horizontal to a vertical orientation as the can drops into the can receiver.

Referring to FIG. 13A, the linear actuator 1010 of the can lift device (906 a-e, FIG. 10) is disclosed.

In embodiments, the can lift device 906 may include a linear actuator 1010 driven by a stepper motor 1108 at the base of the linear actuator. For example, the can receiver 1008 may attach to, and extend below, a sliding carriage 1302 configured for vertical travel along a carriage track 1304 and threaded captive rod 1306; the can receiver must extend below the sliding carriage in order to reach a low enough position to receive the canned beverage 120 from the conveyor (1002, FIGS. 12A-C). In some embodiments the can lift device 906 is configured to lift items that are not cans, but bottles, cups and/or other containers.

Referring to FIG. 13B, the linear actuator 1010 a may be implemented and may function similarly to the linear actuator 1010 of FIG. 13A, except that the stepper motor 1108 may be disposed at the top end of the carriage track 1304. In embodiments, the positioning of the stepper motor 1108 atop the carriage track 1304 may provide for a smaller can receiver 1008 a aligned with, or disposed slightly above, the sliding carriage 1302.

Referring to FIG. 14, the beverage dispensing station 600 b may be implemented and may function similarly to the beverage dispensing stations 600, 600 a of FIGS. 6 and 7, except that the beverage dispensing station 600 b may incorporate a dedicated narrow section air chiller system 1400 adjacent to the selection and delivery mechanism 900. The narrow section air chiller system 1400 may include recirculating air return 1402, recirculating air supply 1404, ambient air condenser 1406 and condenser fan 1408, exhaust vent 1410, chiller evaporator 1412 and evaporator fan 1414, and compressor system 1416.

In embodiments, the air chiller system 1400 may provide air-over chilling of an enclosed compartment within the beverage dispensing station 600 b, and thus chilling of beverage carts (100, FIG. 1) stowed or secured within the enclosed compartment. In some embodiments, the air chiller system 1400 and beverage cart 100 may be configured for “air-through” direct chilling of the beverage cart 100 and its contents. For example, the air chiller system 1400 may be deployed if the aircraft or vehicle aboard which the beverage carts 100 are stowed or utilized is not otherwise equipped with a galley-based air chiller system.

In embodiments, ambient air (1418) may be drawn into the condenser 1406 by the condenser fan 1408 to remove the latent heat from expanded refrigerant gas, allowing the gas to recompress and liquefy. The surplus heated ambient air may be vented (1420) out of the beverage dispensing station 600 b, e.g., into an air extraction duct.

In embodiments, a recirculating chilled air supply 1422 may be drawn into the air chiller system 1400 through the air return 1402 and through the chiller evaporator 1412 by the evaporator fans 1414. The chiller evaporator 1412 may be chilled by, e.g., the reliquification of the refrigerant gas chilled by the condenser 1406 and rapid expansion through a flow control valve (e.g., thermostatic expansion value (TXV)). Chilled recirculating air may be returned to the enclosed compartment via the air supply 1404.

In some embodiments, the enclosed compartment within the beverage dispensing station 600 b may be chilled via any appropriate compact alternative means.
